RGB and Gesture Sensor
######################
Overview
********
This sample utilizes APDS-9960 Sensor and reads RGB values from the sensor
then displays the color through the APA102C LED.
.. note::
This sample does not use the Zephyr sensor APIs
Wiring
******
The SparkFun RGB and Gesture Sensor was being used:
- https://www.sparkfun.com/products/12787
- https://www.adafruit.com/product/2343
For APA102C, on the sensor subsystem (ARC) side of Arduino 101:
1. GPIO_SS_2 is on AD0 (for APA102C data)
2. GPIO_SS_3 is on AD1 (for APA102C clock)
The GPIO driver is being used for bit-banging to control the APA102C LED.
The APA102/C requires 5V data and clock signals, so logic level shifter
(preferred) or pull-up resistors are needed. Make sure the pins are 5V
tolerant if using pull-up resistors.
.. important::
The APA102C are very bright even at low settings. Protect your eyes
and do not look directly into those LEDs.
Building and Running
********************
This sample can be built for multiple boards, in this example we will build it
for the Arduino 101 board:
.. code-block:: console
$ cd samples/sensors/apds9960
$ make BOARD=arduino_101_sss
$ make BOARD=arduino_101_sss flash # with JTAG
.. or
$ dfu-util -a sensor_core -D outdir/arduino_101_sss/zephyr.bin # with DFU
